In mid-September, General MacArthur brought off a masterstroke by landing two divisions 240km (150 miles) in the enemy rear at the port of Inchon. Their communications cut, and under heavy aerial bombardment, the North Koreans broke and fled back north; MacArthur ordered a hot pursuit which led across the 38th parallel and deep into North Korea. As the victorious UN forces drew near to the Manchurian border, there were ominous signals from Peking that communist China would intervene to defend its territory. In mid-October, MacArthur met President Harry Truman on Wake Island in their first encounter to assure him that a massive UN offensive was about to conclude the war victoriously by Christmas. No sooner had this been launched in November than the Chinese unleashed their armies.
On the Western Front during the First World War, the military employed specialist miners to dig tunnels under No Man's Land. The main objective was to place mines beneath enemy defensive positions. When it was detonated, the explosion would destroy that section of the trench. The infantry would then advance towards the enemy front-line hoping to take advantage of the confusion that followed the explosion of an underground mine.
Soldiers in the trenches developed different strategies to discover enemy tunnelling. One method was to drive a stick into the ground and hold the other end between the teeth and feel any underground vibrations. Another one involved sinking a water-filled oil drum into the floor of the trench. The soldiers then took it in turns to lower an ear into the water to listen for any noise being made by tunnellers.
It could take as long as a year to dig a tunnel and place a mine. As well as digging their own tunnels, the miners had to listen out for enemy tunnellers. On occasions miners accidentally dug into the opposing side's tunnel and an underground fight took place. When an enemy's tunnel was found it was usually destroyed by placing an explosive charge inside.
Mines became larger and larger. At the beginning of the Somme offensive, the British denoted two mines that contained 24 tons of explosives. Another 91,111 lb. mine at Spanbroekmolen created a hole that afterwards measured 430 ft. from rim to rim. Now known as the Pool of Peace, it is large enough to house a 40 ft. deep lake.
In January, 1917, General Sir Herbert Plumer, gave orders for 20 mines to be placed under German lines at Messines. Over the next five months more than 8,000 metres of tunnel were dug and 600 tons of explosive were placed in position. Simultaneous explosion of the mines took place at 3.10 on 7th June. The blast killed an estimated 10,000 soldiers and was so loud it was heard in London.
